SPECIFICATION forming part of Letters Patent No. 731,370, dated June 16, 1903. I

Application filed May 28,1900. Serial No. 18,275. (No model.)

To alZ whom it may concern Be itknown that I, CHARLES FRANcIs J EN- KINS, a citizen of the United States, residing at Washington, in' the District of Columbia,

-generators of steam-motors; and my invention consists of means whereby to facilitate the starting of the burner and to light the same after the burner has been extinguished by the action of the regulating devices or otherwise and to maintain the heat of the water inthe boiler, as fully set forth hereinafter and as illustrated "in the accompanying drawings, in which- A r 1 Figure 1 is a longitudinal section of the body of a vehicle, illustrating 'my improve ment.

and burner. Fig. 3 is a vertical longitudinal section, enlarged, of the boiler and burner.

Fig. 4 is a detached view of the supplemental burner-casing of the nozzle in section. Fig. 5 is a plan of the parts shown in Fig. 4.

In the body X of the vehicle is supported the boiler A, below which is the burner B, these two parts being of any suitable construction; but, as shown, the boiler has vertical fire-tubes, is separated fromthe burner B by an intermediate chamber a, and the burner B has vertical air-tubes with surrounding burner-openings, vapor being injected into the interior of the burner from a nozzle 6 to an air-tube g, as in the well-known .Stanley burner. T

In motors propelled by steam-engines objection has been made to the appearance-of the vapor resulting from discharging the exhaust into the Open air. To avoid this objection and also avail myself of the heat of the exhaust-steam, I conduct the steam from the usual Inuflier D through a pipe it into a chamber a; in the casing j below the burner B, so that the exhaust-steam is carried upward with the air to the flame of the burner, and increases the draft, and insures a more rapid combustion, and avoids the appearance Fig. 2 is a front view of the boiler:

of discharge vapor before referred to. It

should be understood, however, that the burner is supplied with air and vapor and will remain in effective operation independently of the exhaust-steam, which merely increases the efficiency of the burner, while its main object is to prevent the appearance of the exhaust-steam about the vehicle.

The casing j may be of any suitable construction; but, as shown, it has a cylindrical flange j fitted to the casing of the burner, and two scoops 7' are formed at the bottom, open at their forward ends, so as to catch the air in running, and the exhaust-pipe h terminates in nozzles t opposite said scoops.

In order to avoid the necessity of using detachable means for starting the burnerthat is, to secure the vapor to supply the nozzle e, without which vapor the burner B cannot operateI make use of a vaporizer, shown as a bent tube f, forming a part of the supplytube D, and a burner G, which receives oil or vapor from said supply-tube, which recei es its supply of oil from a tank F, suitably disposed. As shown, the bent portion f of the supply-tube D is arranged within a perforated casingn within the combustionchamher a, and the end of the tube communicates through a valve-casing m with the burner G, which is an ordinary Bunsen burner, provided with a regulating-valve e and so arranged as to project the flame into the end of the casing or tube at in the chamber a. The casing 'm also communicates through a lateral pipe with the nozzle e and is provided with a control-valveq, regulating the flow to the nozzle, and the valve 1' of a pressure-governor H serves as a means for opening and closing the nozzle e, according to the pressure in the boiler.

Below the burner G is a pan 1), soarranged that when in starting the valve (2 is slightly opened for a moment. a small portion of oil may flow into the pan p, to be there ignited to heat the casing of the burner G. After the casing of the burner G is sufficiently hot the valve 6 is opened, when the oil flowing to the casing will be vaporized and the flame will be projected onto the vaporizer f, so that in a very few minutes all the oil passing to the vaporizer 1 will be vaporized, when the valve g may be turned to open communica-.

auxiliary burner into said casing and the main burner will at once begin to heat the boiler. The action of the main burner also serves to heat the vaporizer f, the surrounding tube or casing, however, preventing the vaporizer from being burned, and the flame of the auxiliary burner G may then be reduced to a minimum.

It will be seen that the pilot-flame from the auxiliary burner is not hot enough to burn the vaporizer-pipe nor to increase the steampressure after the main flame is cut off, and the sleeve 12 while protecting the vaporizer from the main flame conducts thepilot-fiame to a position above the main burner and prevents it from being deflected.

The valverof the governorHis constructed to close the nozzle 6 when the pressure in the boiler reaches the predetermined point, when the light of the main burner will at once be extinguished. This will prevent the pressure from increasing in the boiler; but as the light of the auxiliary burner G is maintained it will serve as a pilot-light to ignite the main burner as soon as the pressure is sufficiently reduced to open the valve 0".

It will be seen that the vaporizerf constitutes the vaporizer for the supplemental burner, as well as the vaporizer for the main burner.

Without limiting myself to the precise construction and arrangement of parts shown, I claim 1. The combination with a boiler, a burner, an intermediate chamber, a supply-pipe extending into said chamber, and a perforated sleeve surrounding the supply-pipe within the chamber, of an auxiliary burner arranged to project the flame longitudinally into said sleeve, substantially as set forth.

2. The combination of a vapor-burner, a chamber above the burner, a nozzle for supplying vapor to the burner, a supply-pipe communicating with the said nozzle and eX- tending into said chamber, a perforated tube inclosing the supply-pipe within the chamber, and a supplemental burner arranged to project a flame upon a part of the said pipe in said tube and also to afford a pilot-light for the main burner above the latter, substantially as set forth.

3. The combination of a boiler, vaporburner beneath the same provided'with a mixing-tube, a vaporizer extending between the boiler and burner, nozzle opposite the mixing-tube and communicating with the vaporizer, a casing f inclosing the space between the boiler and burner, and a Bunsen burner supplied from the same source of supply as the main burner and arranged opposite an opening to project a flame into the casing upon the vaporizer, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
